AD9764ARRL

Digital To Analog Converters Overview

The AD9764ARRL7 is a 14-bit, 125 MSPS TxDAC® digital-to-analog converter manufactured by Analog Devices Inc. It features differential current outputs with a nominal full-scale range of 2 mA to 20 mA and operates on a single supply voltage between 2.7 V and 5.5 V. The device integrates edge-triggered input latches and an internal 1.20 V temperature-compensated bandgap reference. Key performance metrics include a settling time of 35 ns (to 0.1%), INL of ±2.5 LSB, and DNL of ±1.5 LSB at +25°C. Power dissipation ranges from 190 mW at 5 V to 45 mW at 3 V, with a power-down mode reducing standby consumption to approximately 25 mW.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and RoHS compliance status. Ensure that any substitute components maintain pin compatibility and electrical specifications if cross-referencing is required for design continuity.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high dynamic performance in low-power environments. The flexible supply range supports both +3 V and +5 V CMOS logic families. Consider the internal reference bandwidth limitations when designing for high-speed multiplying applications or wide output swing requirements.

Digital To Analog Converters Part Context

The AD9764 is part of the TxDAC® family, which includes pin-compatible 8-, 10-, and 12-bit variants. This architecture allows designers to scale resolution and performance up or down while maintaining consistent interface options and footprint, simplifying board layout and inventory management across different product tiers.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes include the AD9764ARUZ (equivalent parameter version). Verify pinout and thermal characteristics when replacing the ARR variant with other package types within the same series.
